Huge Solar Flare Disrupts GPS Satellites Globally

❝ The Sun’s impact on weather here on Earth is clear: It makes it hot or cold, it powers air currents, it causes water to evaporate making rain, et cetera. But with our increasing reliance on satellites and electronics, you can’t forget its more insidious effects — and some satellites got a taste of those…

Around 5:10 and 8:00AM eastern time, the Sun let out a hiccup and then a loud belch — the largest solar flare in twelve years. These large events are typically harmless to those on the ground, but this one could have potentially disrupted GPS communication yesterday morning.

❝ The flares came from part of the sun called AR 2673…The two flares fell into the X class of most powerful events, one registering an X2.2…and the second registering an X9.3…This second flare was the largest since 2005, and the eighth-largest on record.

These flares come as the Sun is weakening in its 11 year cycle, and X9.3 is especially intense as solar activity approaches its minimum. According to reporting by New Scientist, the storm temporarily disrupted GPS and radio communications…

❝ Space weather isn’t something you necessarily need to worry about, but it’s definitely something engineers and anyone involved with electronics needs to consider…

There’s even an “oops” moment where the article provides a rationale for Trump’s ignorant maundering about vote recording. Not that facts have much to do with his thought processes.

  1. Richard Carrington says:

    The sun emitted another significant solar flare from Active Region 2673, peaking at 12:06 p.m. EDT on Sept. 10, 2017. https://www.nasa.gov/feature/goddard/2017/active-region-on-sun-continues-to-emit-solar-flares To see how this event may affect Earth, go to NOAA’s Space Weather Prediction Center at http://spaceweather.gov, the U.S. government’s official source for space weather forecasts, alerts, watches and warnings. This flare is classified as an X8.2-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
